Western Digital is now shipping its 250 GB WD Scorpio™ 2.5-inch Serial ATA (SATA) hard drives. The drives employ perpendicular magnetic recording (PMR) technology to achieve the highest capacity available in a small form factor drive and have WD proprietary features that make the drive quiet, use less power and run at cool operating temperatures. The new WD Scorpio drive further expands the company’s breadth of 2.5-inch mobile hard drive offerings to capacity points ranging from 40 GB up to 250 GB. Estimated pricing is $ 199.99 USD

Western Digital Corp. (NYSE: WDC) today announced it is now shipping its 250
GB WD Scorpio™ 2.5-inch Serial ATA (SATA) hard drives. The drives employ
perpendicular magnetic recording (PMR) technology to achieve the highest
capacity available in a small form factor drive and have WD proprietary features
that make the drive quiet, use less power and run at cool operating
temperatures.

“The 2.5-inch market continues to be a major focus for WD, and this 250 GB WD
Scorpio drive represents our second-generation PMR platform,” said Jim Morris,
WD’s vice president and general manager of notebook storage. “The WD Scorpio 250
GB hard drive is a direct result of the significant investments WD has made in
proprietary head technologies as well as significant system level feature
innovation. With the introduction of our latest-generation WD Scorpio drives, WD
continues to offer mobile computing and portable storage customers the same
outstanding quality, reliability and performance that have earned the company a
leadership position in the desktop PC market.”

According to market research firm, IDC, adoption of PMR technology in mobile
2.5-inch hard drives will sustain an increase in the average capacity shipped
close to the average growth rate of 32 percent for the past five years. The firm
states that by 2011, shipments of mobile 2.5-inch hard drives will more than
double 2006 shipment volumes.*

Demand for 2.5-inch hard drives continues to increase at a rapid pace, driven by
notebook computers, portable storage devices and consumer electronics products.
Users of these applications need high capacity drives to manage storage-hungry
content. WD Scorpio drives deliver the performance and features to meet demands
that are specific to notebook PCs and portable storage devices, such as WD
Passport® portable drives: quiet operation, high shock tolerance and low power
consumption.

The new WD Scorpio drive further expands the company’s breadth of 2.5-inch
mobile hard drive offerings to capacity points ranging from 40 GB up to 250 GB.

WD Scorpio Exclusive Features
WD’s exclusive WhisperDrive™ technology combines state-of-the-art seeking
algorithms to yield it one of the quietest 5400 RPM, 2.5-inch drives available.
Leading-edge ShockGuard™ technology combines firmware and hardware advancements
to protect the drive mechanics and platter surface to meet the highest combined
shock tolerance specifications required for mobile and notebook applications.

Another unique WD Scorpio 250 GB feature is its IntelliSeek™ technology, which
proactively calculates an optimum seek speed to eliminate hasty movement of the
actuator that produces noise and requires power, which is common in other
drives. With IntelliSeek, the actuator’s movement is controlled so the head
reaches the next target sector just in time to read the next piece of
information, rather than rapidly accelerating and waiting for the drive rotation
to catch up. This smooth motion reduces power usage by more than 60 percent
compared with standard drives, as well as quiets seek operation and lowers
vibration.

About PMR
With PMR technology, the magnetization of each data bit is aligned vertically to
the spinning disk, rather than longitudinally as has been the case in hard drive
technology for decades. This enables more data on a given disk than is possible
with conventional longitudinal recording, and provides a platform for future
expansion of hard drive densities.
